I still  maintain that its best to do tessellations using pencil, paper, 
cardboard, tracing paper etc.

Why?
Because there is no easy way, for instance, in Logo to do this:-

1. draw an irregular quadrilateral
2. measure the midpoints of each side
3. draw a curved line between the vertex and midpoint
4. rotate that curve to the vertex at the other end of the line

etc.

By using the computer you restrict the range of tessellations that students can 
do. Last time I looked MicroWorlds could handle the translations but not the 
rotations.

Shouldn't we use the best medium available for a given task?

Dale Seymour Publications have some brilliant books on tessellations (including 
one called 'Tessellations using logo' which I don't use). Sorry, can't remember 
the title of the one I do use.

btw, Escher didn't use a computer !
